Hydrometallurgy is an efficient way of recovering metal ions from mineral ores where the
most important steps are the leaching of the minerals, the recovery and purification of metal …

This review addresses research and development on the use of ionic liquids as extractants
and diluents in the solvent extraction of metals. Primary attention is given to the efficiency …

In the present work, two novel ammonium-based functional ionic liquids (FILs) with oxygen
donating groups: trioctyl (2-ethoxy-2-oxoethyl) ammonium dihexyl diglycolamate,[OcGBOEt] …

In this review, the performance of ionic liquids (ILs) as separating media for selective and
sustainable extraction of rare-earth elements (REEs) is analyzed. ILs as solvents have been …

Among ionic liquids, phosphonium-based ionic liquids (PILs) are quite elegant. These
categories of ionic liquids represent some merits over other types of ionic liquids such as …

Rare earth metals (REMs), especially neodymium, samarium and europium are termed as
critical metals since their supply is experiencing shortfall due to sudden rise in demand …

The present review covers achievements in the development and application of
phosphorous-containing extractants for varios metals. The extractants based on industrial …

Recovery and separation of rare earth elements was highly crucial but difficult. In this study,
a well-designed new ionic liquid named as benzyltributylammonium decanedioate ([N …

Processing of end-of-life products has become essential in the rare earth elements (REEs)
recovery field because the demand for these metals has increased over the last years due to …

One of the main difficulties to achieve a good performance with the emulsion liquid
membranes technique for metal extraction is the solvent phase recovery. In the present …
